Designed a simple and efficient layering swatch for testing 2 colours.

There are 2 options:

1. 0.08 mm to 0.2 mm
2. 0.00 mm to 1.2 mm

There's only 1 filament change, and you can do both tests together if you want to.

The height starts at the top-right colour, then increases by 0.02 as we go in a clockwise spiral. I've included a labeled image for easier reference.

I've also included a “micro” version, which is the same thing but much smaller.
